Osteoporosis is a condition that makes bones weak and prone to fractures. As you age, the rate of bone loss may outpace the formation of new bone, leading to weaker bones. Early treatment can prevent severe consequences like height loss or fractures. Common symptoms include receding gums, brittle nails, and back pain or hunching from spinal compression fractures. Preventive measures include regular exercise, adequate calcium and vitamin D intake, avoiding smoking, and excessive alcohol consumption. Regular bone density tests are also important. If at risk, medications like bisphosphonates or hormone therapy can be used for treatment.
